ULA chief says Vulcan rocket will slip to 2024 after ground system issues

Bruno made the announcement after the company attempted to complete a fueling test of the entire rocket, known as a wet dress rehearsal.

“Vehicle performed well,” Bruno wrote. “Ground system had a couple of (routine) issues, (being corrected). Ran the timeline long so we didn’t quite finish. I’d like a FULL WDR before our first flight, so XMAS eve is likely out. Next Peregrine window is 8 Jan.”
